In late January 2013, Creator played his Code S round of 32 matches of the 2013 Global StarCraft II League Season 1. Facing Life, Symbol and ByuL, it looked as a promising start for the Prime Protoss, having had a two month break from his last official match to train and prepare for only one matchup. After decidedly dispatching ByuL 2-0, Life proved too strong for him, beating Creator with back-to-back unorthodox two base play.
